Heishi means shell and in the past, referred to pieces of shell that have been drilled and hand rolled or ground into bead shapes and strung as necklaces. With the reduced availability of some shell materials, the modern Native American artists also use hand made beads of other natural materials including stones when making heishi necklaces.
The shells most commonly chosen for heishi include penn shell, olive shells, spiny oysters, mother-of-pearl (MOP), and melon shell. Coral is also used as well as stones such as lapis, turquoise, jet, pipestone, and serpentine. Heishi beads are made by slicing the shell or stone into uniform strips.Then the pieces are nipped into small squares. Each square then has a hole drilled in it. The squares are strung, each material being strung in a separate group. The strings of squares are smoothed and rounded by grinding and rolling the beads.he shells most commonly chosen for heishi include penn shell, olive shells, spiny oysters, mother-of-pearl (MOP), and melon shell.
